|Buff-fronted Owl at Dourado, São Paulo State, Brazil|
The buff-fronted owl (Aegolius harrisii) is a small owl, a rare and local resident in the highlands of South America from Venezuela south and east to Peru, northern Argentina, and northwest Paraguay. Its range is effectively separated into two parts by the unsuitable habitat of the Amazon basin.
The buff-fronted owl is a small, compact, short-tailed, and broad-winged owl, approximately 23 cm long and weighing approximately 130 g. It is black above with white flecking on the wings. The underparts are unstreaked buff and the tail is brown with two spotted white bars. The head is large, with yellow eyes and a black-edged buff facial disc. The flight is strong and direct. The voice is a quavering trill sometimes varying in pitch.
The buff-fronted owl was described by the American ornithologist John Cassin in 1849, and given the binomial name Nyctale harrisii. The binomial commemorates the American ornithologist Edward Harris.
